i would recommend IE 9 .
IE 9's engine Best utilizes the Hardware Acceleration to render the graphics .
better than Chrome and Firefox , as of now .

visit this website - http://ie.microsoft.com/testdrive/Performance/FishIETank/
and open it in various browsers and see how many FPS you are able to get in each of the browsers which displays the site .

you will see the difference ..

the FPS would be displayed in the top right corner of the web page .

Chrome has it's own game store : https://chrome.google.com/webstore?category=app%2F3-games

Angry bird was available on chrome only.

I think you should have the latest updated version of any browser. so it can be compatible with your games.
the performance of the browsers may depend on the platform of the game.

chrome, firefox.If a game not works with one browser, try with the other.
